Just got back the SR22 I sold to a friend 4 years ago. It is one of the earlier models and, according to Rugers website, their threaded barrel will not work with mine. Twin Tech Tactical makes an OEM and long barrel (both threaded) for the SR22. Anyone have one? How do you like it? Read on another forum that someone suggested getting the long barrel (hangs 1/2" out) because it is easier taking the thread protector on and off than with the OEM barrel. Thoughts?
